I Specification of Iletters Patent. I Patented Aug.23, 1910- Application filed Kay 5, 1909. Serial No. 494,183.

To all whom it may concern:

Be it known that I, DANIEL J. MURNANE, a citizen of the United States, residing at- St.- Louis, Missouri, have invented a certain new and useful Im rovement in Ventilated Window-Frames, 0 which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to window frames, and particularly to that type which are provided with ventilatin openings.

The main object 0 my present invention is to provide a window-frame of the type referred to which is so constructed that the ventilating openings cannot be seen from the outside of the window.

Another object is to provide a ventilated window frame in WhlCh the ventilating openings are arranged in such a manner that water or moisture cannot pass through same into the interior of the window. And still another object of my invention is to provide a ventilated window frame that presents a neat and ornamental appearance.

Figure 1 of the drawings is'a front elevational view of a wooden window frame constructed in accordance withjmy invention; Fig. 2 s an enlarged cross sectional view taken on the line 22 of Fig. 1; and Fig. 3

is a cross sectional view illustrating my in-- vention embodied in a metallic window frame.

Referring to Fig. l of the drawin s, 1 desaceof the wall 0 a building, and 2 designates a wooden window frame that is set into said wall, said frame being used for supporting a plate .of glass 3 that is retained in position by means of outside clamping pieces 4 that are connected to the frame 2 in any suitablemanner. The

top, bottom and side pieces of the fraine 2 tare rovided with ventilating openings 5 whic extend from the inside of the frame to the outside thereof so that air can pass through same and thus ventilate the room or compartment which the window closes. The outer edge of the frame 2 is provided with a rabbet or groove 6 that extends completely around same so as to form a channel between the frame and the wall 1 inwhich it is ar-- ranged, and the outside clamping pieces 4 which retain the plate of glass in position are so arranged that they w1ll not completely cover this channel. The outer ends edge of the frame.

the arrows in Fig. 2 p from through the-slot 13 formed between of the ventilating openings 5 terminate at so as to thoroughly ventilate said compart' ment but the ventilating openings cannot be seen from the outside of the window because they terminate at the side wall of the groove or rabbet 6 which is formed in the outer in shown,'-the channel or groove 6 between the frame 2 and the wall 1 is proportionately larger than is used in actual practice so. as to more clearly set forth my invention. Still another desirable feature of a window frame of this construction is that water or "moisture cannot pass through the ventilating openings 5 as said openings are inclined downwardly from the interior to the exterior of the frame 2, as shown in Figs. 1

and 2.

In Fig. 3 have illustrated a metallic window frame constructed in accordance with my invention, said frame being composed of metallic outside clamping pieces 7 and inside clamping pieces 8 between which the plate of glass is arranged. The wall 9 in WhlCh the window opening is formed, has an approximately L-shaped metallic member 10 connected thereto so as to form the bottom In the illustration here-- and rear wall of a ventilating chamberwhose top and front walls are formed by the clamping members 8 and 7, respectively, the inside clamping member 8 being carried by a number of supports 11 on which the lower edge of the plate of glass rests. These supports 11 are arranged inside of the ventilating chamber and are spaced away from each other so, as to not interfere with the passage of the air into and out of the ventilating chamber. The lower edge of the outside clamping piece 7 terminates a short distance above the horizontal leg of the L- shaped metallic member 10 so asto form a narrow slot 12' that permits the air to pass into the ventilating chamber, as shown by and thus escape there able.

member 10, thus thoroughly ventilating the room .or compartment which the window closes.

The main advantage of a construction of the character just described is that no ventilating openings can be seen from outside of i the window, the slot 12 which admits the air being so narrow that it is not notice- In view of the fact that this slot 12 is continuous it is not as liable to become clogged with dirt as the constructions ofthis characterthat have heretofore been in use which were provided with a number of spaced holes or openings for admitting air into the window.

YVhile I have herein shown an L-shaped member 10 and clamping pieces 7 and 8 arranged at only the lower edge of the plate of glass, it will, of course, be understood that this same construction .could extend all around the window and therefore I do not wish it to be understood that my broad idea is limited to a construction in which a ventilating chamber is arranged at only the lower edge of the plate of glass. I have not herein shown any means for retaining the outside clamping piece 7 in position for it is immaterial so far as my present invention is concerned how said clamping piece is held in position. I also wish it to be understood that my broad idea is not limited to the exact construction shown in Figs. 1 and 2. for, if desired, the groove or channel 6 which extends around the frame could be formed by using an outside clamping piece formed in the outer edge of the frame.

2. window frame having ventilating openlngs that extend from the interior to the exterior thereof, and a channel formed between the frame and the wall or member in which it is arranged, the outer ends of said ventilating openings terminating at one wall of said channel in such a manner that they cannot be seen from outside the window.

3. A window frame provided in'its outer edge with a groove or rabbet that forms a channel between the frame and the Wall or member in which it is mounted, and ventilating openings in said frame that incline downwardly from the interior of said frame and terminate at one wall of said channel in such manner that they cannot be seen from outside the window.

In testimony whereof I hereunto afiix my signature in the presence of two witnesses, this first day of May 1909.

DANIEL J. MURNANE.
